Based on this study, it can be concluded that onion yield is highly dependent on the amount of water applied. Key words: Deficit irrigation, Water productivity, Water use efficiency 展开 关键词: Water use efficiency Deficit irrigation sprinkler irrigation 被引量: 3 年份: 2012 ...
deficit irrigation in northern China based on previously published studies. The result shows that deficit irrigation results in an average yield reduction of 7.10% for wheat and an average yield reduction of 18.71% for maize, while the average water use efficiency (WUE) increases by 9.25% and ...
Deficit irrigation (DI) has been emerging as an important technique for enhancing crop water productivity (WP). However, advantage of DI under varying nitrogen (N) application rates remains unclear. Field experiments were conducted during 2012–2014 to investigate the impacts of six irrigation levels...
Given the current pressures to reduce irrigation water use, it is important to optimize the use of water in irrigated agriculture. This work was aimed at determining the optimum level of applied irrigation water (AIW) for cotton (Gossypium hirsutum L.) production in southern Spain under several ...
Regulated deficit irrigation (RDI) is key technology because it helps to improve water use efficiency. Nonetheless, there is a lack of understanding of the mechanisms with which plants respond to RDI. In particular, little is known about how RDI might increase crop production while reducing the ...
